To oli wil-om t may concern."

Be it known that l. Amman F. KRAMER, a citizen of the United States of America. residing.' at l `reedonny in the county of Beaver and State of Pennsylvania, have invente/.l certain new and useful li'nprovements in Tires, of which the following is a specifieation. reference being had therein lo the accompanying drawing.

This invention relates to tires and more v particularly to that type of tire used in connection with automobiles and similar vehicles.

The objects of my invention are to dispense with the use of pneumatic tires and provide a solid rubber tire with novel means for cushioning the same upon the telly or rim of a wheel, and to provide a` dust-proof. non-penetrable tire that can be readily used in connection with the present type ot automobile wheel.

Further objects ot the invention are to utilize springs in connection with wheel for cushioning a solid tire7 the springs being arranged whereby they 'ill cooperate in sustaining a load upon the axle ot a wheel. and to accomplish the above results by a mechanical construction that is simple,l durable."easy `to repair and etlicient for the purposes for which it is intended.

lV ith these and such other objects as may hereinafter appear. the invention consists of the novel construction, combination and arrangement ot parts to be. hereinafter specifi cally described and then claimed.

Reference willnow be had to the drawings fori'ning a part oi' this specification. wherein there are illustrated the n'eterred embodimentsl of the invention,` but it is to be understood that the structural elements thereotl can be varied or changed without departing from the spirit and scope ot' the invention.

ln the drawings z-Figure 1 is a. side elevation of a wheel in accordance with this invention. partly broken away and partly in section. Fig. Q is a cross sectional view of a portion o't the wheel. F ig. 3 is a perspective view of a portion ot the telly and rim of the wheel, Fig. d is an enlarged cross sectional view of a portion of the wheel. Fig. 5 is a similar view of a modified form of wheel, and( Fig. 6 is a similar view ot another modifiedA form o't wheel. f

ln the accompany-ing drawings the reterence numeral 1 denotes a hub having a plurality of radially disposed spokes 2 mounted in the inwardly projecting sockets 3 of a channel shaped telly si, said telly being arranged CirCmnterentially'of the spokes and opposite each socket thereof provided with an opening 5 having the walls thereof threaded. The channel shaped telly L1- has the side flanges G thereof provided with a plurality. of oppositely disposed vertical grooves T.- the purpose of which will pres ently appear.

S denotes al rim of a greater diameter than the telly at. said rim having the edges thereof provided withihooitfshaped flanges 9 and inwardly projecting flanges 10, said flanges being arranged in pa allelism toengage the outer edges ot the flanges G of the telly 4. The rim 8 is made of a single piece of metal rolled to the desired shape and the ends thereof connected by plates 11 and rivets 12, said plates being arranged upon the inner sides of the flanges '10. The inner sides of the flanges 10 are provided with a plurality of radially disposed guide bars 13 retained in engagement with the tlanges by bolts 14 and nuts 15, or other fastening means'. These guide hars are adapted to engage in the grooves 7 of the telly l and guide the movement ot' the rim S relatively to Said telly. The rim provided with aplurality of equally spaced openings 16 and extending through these openings are the threaded ends 1T olf .foiled compression .springs 18, said springs havingthe .opposite ends 19 thereof mounted in the opei'lings The threaded ends 17 ot the springs extend through the openings 1G and are provided with-nuts 20, thus permitting the parts of the tire being easily and quickly assembled.

The llanres 9 of the rim 8 serve functionally as a eleneher for holding the circumferentially and beaded edges 21 of a resilient tire QQ, said tire being preferably made ot rubber with the inner side thereof cut away to form recesses 23, these recesses providing clearance for the nuts Q() and the threaded ends 17 of the springs 18.

Tn Figs. 5 and -6 of the drawings there are illustrated modifications of the manner of attaching the tire to the rim, for instance in Fig. 5, the tire 24. oval-shaped in cross section is mounted in a circuinterentially arranged groove 25 'formed in an enlargement Q6 ot the rim S, while in Fig. G of the' drawings the flanges 9 and the enlargement QG are dispensed with and the outer side of the rim 8 provided with a plurahty of lpins or bearings 27 adapted to engage in the flat side 2S of ,a tire 'that is substantially the tire 22 when upon the hub l.

The hub l, spokes 2 and felly 4 are of the conventional form at present used, and to linstall-my improved tire it is only necessary 'to provide the .felly with the grooves 7.

The :telly 4, rim 8, springs l18 and the remaining parts of the structure, with the except-'ion of the tire 22 are'made ofv strong and durable metal and it is immaterial as to the type of fastener employed for retainin the tire 22 upon the rim 8.

v:wing non7 described .my invention what I claim as new, is

A tire for Wheels comprising a felly having its sides formed Withgrooves-and further provided centrally thereof wit-hn circumferentially extending row of openings having threaded walls, a having in- WardlyI projecting' flangesf'engnvinr the sides of said fellby `and further Dprvided with a centrally disposed circumferentially extending row of openings, a tread carried by said rim, coiled compression springs in-` terposed between said rim :1nd felly and having their inner ends `threaded for engagement with the threads of the Walls of the .openings of the felly and their outer ends loosely extending through the o en-k ings of the rim, nuts carried by the enr. s ofA the springs which extend through the rim wherebyvthe springs are loosely connected With the rim, and bars carried by the inner,

side of the flange of the rir'n :und slidable through the grooves of the felly. f

In testimony whereof I alix my signature in the presence of two Witnesses.
